This invention relates to metallic weather strips for windows, and has for the primary object the provision of strips so constructed that they will efliciently seal a window frame and the sashes thereof to the passing of air between said frame and the sashes and will greatly facilitate the sliding of the sashes in the frame and also act to check rattling of the sashes either when open or closed and may be easily and quickly installed with the use of nails or like fasteners reduced to a minimum, employing primarily the parting strips of the frame to secure the weather strips in place with double contact with each sash.

With these and other objects in View, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a front elevation illustrating a window frame and its sashes equipped with weather strips constructed in accordance with the present invention.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a fragmentary sectional view taken on the line 3-3 of Figure 1.

Figure 4 is an enlarged fragmentary transverse sectional view of the check rail of the upper sash showing one of the weather strips of the present invention adapted thereto.

Figure 5 is an enlarged fragmentary transverse sectional view showing one of the weather strips of the present invention secured in place on the frame by the horizontal parting strip thereof and the grooves of the frame employed to receive said parting strip.

Figure 6 is a fragmentary transverse sectional view showing one of the weather strips of the present invention adapted to the lower rail of the lower sash of the window.

Figure '7 is a perspective view illustrating one of the weather strips employed on the vertical parting strip of the window frame to have double contact with the sash.

Figure 8 is a perspective view illustrating the weather strip employed on the check rail of the upper sash.

Referring in detail to the drawings, the numeral 5 indicates a window frame of a conventional construction having the usual sliding upper and lower sashes 6 and I. To adapt the present invention to the window construction as shown in the drawings it is only necessary that the vertical and horizontal parting strips 8 and 9 be removed from their grooves l0 and the lower check rail II of the upper sash 6 be provided with a groove I2 in its bevel face I3 which when the sashes are in window-closing position coacts with a like bevel face of the check rail I4 of the lower sash I in effecting a closure between said sashes.

The primary invention consists of weather stripping I5, IS, IT, and I8, all of which is constructed of a resilient metal. The strip I5 consists of an elongated portion l9 having a slight arcuate curvature thereto and which extends transversely of said portion. The strip I5 further includes an attaching ear 20 apertured to receive a fastener 2| for securing said ear on the top face of the check rail II so that the portion I9 is disposed over a portion of the face I3 of said check rail II and directly in front of the groove I2. When the check rails II and M of the sashes 6 and I come together with their bevel faces opposed the portion I9 seats in the groove I2 and its free edge contacts the bevel face of the check rail I4, that is, as said check rail I and I4 are moving into engagement with each other and when they become fully matched the portion I9 of the strip I5 is flexed substantially straight as shown in Figure 2 so as to provide an efiicient seal between the check rails.

The weather strip I6 consists of a portion 22 of elongated plate-like construction which has a slight compound curvature thereto and which extends transversely of said portion. The strip [6 adjacent one edge is provided with openings to receive fasteners 23 for securing the strip on the under face of the lower rail of the lower sash I. When the lower sash I is raised the free edge of the strip I6 is spaced a distance from the lower rail. However, when coming in contact with the window frame on the closing of the lower sash the portion 22 straightens out and lies flatly against the window frame and the lower rail of the lower sash with considerable pressure against both to effect an efficient seal between the lower rail of the lower sash and the window frame.

The weather strip l'i consists of a resilient sheet of metallic material which is bent upon itself and again bent at right angles to form angularly related portions A and B of double thicknesses. After the bending of the material to form the portions A and B said material is bent to form the portions 24 and 25 which are arranged in diverging relation. The portion 2 3 has a transverse curvature thereto while the free edge of the portion 25 has a slight curvature.

To adapt the weather strip ii to the window frame, the upper parting strip 9 is removed from ts groove it and the portions A and B of the strip I? are laid into the groove. The parting strip is then forced into the groove contacting the portions A and B bringing about firm securing thereof on the Window frame with the pertions 24 and 25 free to engage the upper sash 6 when in full Window closing position. The portion 25 is forced into engagement with the upper wall of the Window frame while the portion 2% is forced against the parting strip and one face of the window sash thereby providing a double contact of the weather strip with the upper sash.

The weather strip i8 is constructed or shaped similar to the Weather strip El and in adapting the Weather strip 68 to the window frame it is employed in pairs and the pairs of weather strips iii are seated in the vertical grooves of the vertical parting strips as clearly shown in Figure 3, the parting strips holding the pairs of weather strips 58 tightly on the frame to contact the upper and lower sashes, the portions 2d thereof engaging both the sashes and the parting strips While the portions 25 thereof engage edge faces of the sashes so that the Weather strips it will contact each sash on two faces thereof with sufficient pressure to prevent rattling of the sashes and to provide a perfect seal between the sashes and the frame and the parting strip.

Thus it will be seen that the weather strips as described in detail and shown in the drawings are simple to construct and easy to apply and only require a minimum number of fasteners for the securing thereof on the frame, the greatest number of the strips being secured in place through the use of the parting strips and their respective grooves.

It is believed that the foregoing description, when taken in connection with the drawings will fully set forth the construction and advantages of this invention to those skilled in the art to which such a device relates, so that further detailed description will not be required.

Having thus described my invention, what I claim is:

In a Window frame having a groove therein, a parting strip having a portion seated in the groove, and a sash; a strip of doubled spring metal having its doubled part located in the groove between a wall thereof and a part of the parting strip with the two free-edge parts of the spring strip projecting from the groove, with one edge part extending along a side face of the parting strip and bowed outwardly with its edge located close to the said side face of the parting strip, the other edge part of the spring strip diverging from the first edge part and normally extending at an angle from that part of the frame adjacent the groove and adapted to be pressed against said part of the frame by the sash, the corner of which fits between the two edge parts of the spring strip, the free edge of said other edge part curving outwardly to contact the sash.
